question to you guys. It's just hint to BOINC scheduler, not any realy CPU usage or CPU usage limit. |

problem is when i look in task manager the cuda app is constantly doing around 12% cpu usage. is that normal? |

problem is when i look in task manager the cuda app is constantly doing around 12% cpu usage. It depends on CPU speed. I looked at your Athlon 64 X2 host results - it seems CUDA part working OK. You could see big CPU usage for CUDA app when it can't properly initialize (low GPU memory or another error) and falls back to CPU processing. This mode should be avoided cause CPU processing by CUDA MB much slower than by AK_v8. But your GPU works OK. |

... You didn't saw my questions? ;-) If you don't have time with a new thread.. Could you please post the URLs of the recommend CUDA Vx apps and .dll's? Then someone of the community could open a new thread because of this.. :-) ![]() |

Could you please post the URLs of the recommend CUDA Vx apps and .dll's? Thanks a lot! Hmm.. but.. what about the rigs with > 1 GPU in it..? Soon also a new app release for this rigs? ![]() |

Could you please post the URLs of the recommend CUDA Vx apps and .dll's? ..hmm.. I misread your post at lunatics.kwsn.net ? I understand it, that this app is ONLY for rigs with 1 GPU. No? ![]() |

Could you please post the URLs of the recommend CUDA Vx apps and .dll's? You read it correct. I updated that post and included builds w/o affinity lock based on current codebase. No actual performance difference should be with last V10/11 update buried in corresponding Lunatic's thread. I did fresh build just for convenience. |

Build w/o VLAR kill mod added to the same post. It should load faster (use less CPU time) than current stock while doing all kind of work stock does. http://lunatics.kwsn.net/12-gpu-crunching/v10-of-modified-seti-mb-cuda-opt-ap-package-for-full-multi-gpucpu-use.msg16715.html#msg16715 (remember that VLAR and VHAR tasks use GPU less effective than midrange tasks, complete data chart in progress). |

Just noticed my gpu temp dropped quite a bit,shows it's running in task manager,but in boinc mgr times went from ~14min to 30min now one running at about 2hrs. I'll do a reboot now and see what happens. edit..After reboot temp went back to normal, also processing time looks regular./edit |

I'm curious.. I had a bunch of VLAR 'killed' WUs.. [52] And BOINC uploaded them like every time.. Then BOINC had a ~ 24 hours break counter in the project overview. [BOINC V6.4.7] Why? BTW. Why the 'killed' VLARs need to upload? ![]() |

The answer is in This thread BTW answer - To let the server know that you are aborting them, otherwise they would have to time out (no response). Editted for correct thread |

http://setiathome.berkeley.edu/forum_thread.php?id=52212&nowrap=true#884686 Because of my 'Out Of Memory' errors.. Some examples: http://setiathome.berkeley.edu/result.php?resultid=1206226503 http://setiathome.berkeley.edu/result.php?resultid=1211721515 http://setiathome.berkeley.edu/result.php?resultid=1212504106 All errors look like this: ------------------------------------------------------- WU true angle range is : x.xxxxxx Unhandled Exception Detected... - Unhandled Exception Record - Reason: Out Of Memory (C++ Exception) (0xe06d7363)* at address 0x7C81EB33 Engaging BOINC Windows Runtime Debugger... ******************** BOINC Windows Runtime Debugger Version 6.3.22 ------------------------------------------------------- I guess now it's not a RAM error it's looks like it's a compiler error.

Compiler error? Don't think so. Maybe it's worth to add dump of available system physical memory too in additional to GPU memory. Will think about it. For now such out of memory behavior could be summoned by buggy stock 6.03 on beta (if I correctly understood Pappa's report). |

This '0x7C81EB33' couldn't be the address of the place of a damaged RAM, or? Like I said, the error output is all the time the same. ![]() |

"at address 0x7C81EB33" This adress the same? Same exception code means same error - out of memory. |

Yes, all the time the same output: ------------------------------------------------ Unhandled Exception Detected... - Unhandled Exception Record - Reason: Out Of Memory (C++ Exception) (0xe06d7363) at address 0x7C81EB33 Engaging BOINC Windows Runtime Debugger... ------------------------------------------------ I'm confused - I'm the only one which see this error in the own overview? ;-) ![]() |
